by a brace 16, the bars being pivoted vat 17 to the arms 9.

The receptacle 11 includes a fixed bottom 18 made up of rods or lingersthe forward ends of which are free. A rear wall 19 is pivotedp at 20 tothe sides of the receptacle 11 and to the bottom- 18 thereof. There is abracket 21 on the rear end of the frame 1 to which a longitudinallyresilient adjustable connection 22 is pivoted. The connection 22includes a bar 23 pivoted at 24 to the bracket 21, the forward end ofthe bar having a socket 25 provided with a slot 26. A bar 27 is pivotedat'28 to the free end of the rear wall 19 and slides in the socket 25,the bar carrying across pin 29 having movement in the slot 26 andlimiting the relative movement of the parts 23 and 27 under the actionofa compression spring 30 which surrounds a portion of the bar 27, ,oneend of the spring abutting against the socket 25, the other end of thespring abutting againstr a collar 31 held adjustably on the bar 27 byAmeans of a set screw 32 or the like.

Doors 33 are united by hinges 34 with the sides of" the receptacle 11and include springs 35 which tend to swing the doors open. Keepers 36are carried by the receptacle 11. Guides 37 are mounted on the doors 33and in the guides, work latches 38 pivoted at 39 to the doors 33, thelatches aving notches 40 which coperate with the keepers 36 to hold thedoors 33 closed, the latches being actuated by springs 41, attached tothe doors, the springs maintaining the latchesyieldably engaged with thekeepers. Arms 42 are secured to the doors 33 and are adapted to coperateat their rear ends with standards 43 on the frame 1. The standards 43include rearwardly inclined lips 44 across which the arms 42 slide, in away to be ydescribed hereinafter, for the purpose of closing the. doors33. Inwardly projecting releasln members 45 are mounted on the sides, othe frame 1 and may be adjusted vertically, the releasing members beingheldin adjusted positions by means of nuts 46 which engage the frame 1.The releasing members 45 cooperate with the latches 38 to'disengage thesame from the keepers 36 in order to permit are loose on the the doors33 to open responsive to thieJ springs 35.

Ay pulley 47 is connected to the ground wheel 2 to rotate therewith,-and is engaged by a belt 48 coperating with a pulley 49 on a shaft50'extended transversely of the frame 1 and journaled thereon. Drums 51nected thereto by clutches 52 operated by levers 53 and 54 fu'lcrumed onthe frame 1, the rear ends of the levers being connected by a link 55,the lever 53 being a-hand lever. Flexible elements 56 are connected vtothe drums 51 and are trained across idlers 57 on the frame 1, theflexible elements being extended upwardly around pulleys 58 on the frame5 and being connected at 59 i with the yerticallyswinging arms 9.

A'. sleefe 60 is vjournaled on the shaft 50 but may be connected theretoby a clutch 61 controlled by a lever 62 fulcrumed on the rear end ofthe.. frame 1. The sleeve 61 carries drums 63 about which are engagedflexible elements 64 secured to the stub shafts v12 on the receptacle11.

One of the vertically swinging arms 9 has an extension 65 projectingrearwardly beyond the pivotal mounting 10 of the said arm, the extensionbeing prolonged laterally as shown in Fig. 4, the part 66 carrying a cam67 which coacts with the clutch lever 53. A rock shaft 68 is journaledon the rear end of the frame 1 and includes a finger 7 0 which overhangsthe bar 23 of the connecy frame 1. The outer tion 22l which unites thepivoted wall 19 of the receptacle 11 with the bracket 21 on the end ofthe rock shaft 68 has an arm 71 terminating in a transverse cam 72coacting with the clutch lever 62.

Let it be .supposed that the receptacle is in a position to receive thesheaves of grain from the binder. Then the parts are arranged as'shownin solid line in Fig. 1.v The doors 33 are disposed at thebottom of thereceptacle 11 and are held closed because the latches 38'on the doorsare engaged with the keepers 36 on the receptacle. The part 18 of thereceptacle 11 is disposed vertically and the swinging wall 19 of the`receptacle is-held in an open position'by the connection 22, the rollers14 on the receptacle being disposed at the rear ends of the horizontalslots 7 in the guides 6, the arms '9 being swung downwardly intoapproximately parallel relation to the sides of the frame 1. The sheavesof grain are now delivered in any desired number into the receptacle 11and collect on the. closed doors 33.

When a shock of sufficient size Vhas ac' cumulated in the receptacle 11,the lever 53 is manipulated to connect the drums 51 with the shaft,A 50by Way of the clutches 52. The

shaft 50 issdriven from the ground wheel 2 by the pulley 47, the belt 48and the 49. The

pulley liexible elements 56 are reeled on shaft 50 but may be c0n `lVhcnthe arms 9. are swung upwardly.

,horizontal slots the drums 51 and, passing over the pulleys 57 and 5elevate the forward ends of the arms 9, the wall19 being closed againstthe shock in the receptacle 11 -by the action of the pivoted` connection22, it being noted that. owing to the presence of the spring 30,

a yieldable pressure on the shock is afforded. l

11 being in a vertical position, the wall 19 I being verticallyvdisposed and the bottom 18 being horizontally disposed. the butt of theshock coming into contact with the ground, between the rods or lingerswhich make up the bottom. Just about the time that the butt of-the shockcomes into contact with the ground, the latches 38 en'gage the releasingmembers 45, the latches being disengaged from the keepers 36, whereuponthe doors 33 fly open under the action of the springs 35. As thestructure moves forwardly, the shock, which is nowl in an uprightposition, passes 0H the bottom 18 of the receptacle .11- andout betweenthe open doors 33, the shock being left standing upright on the ground.

The operator now manipulates the lever 62 and couples the sleeve 60 andthe drums 63 withthe shaft 50, the flexible elements 64 being drawnrearwardly to cause the rollers 14 on the receptacle first to rise inthe depending ends 8 of the guide slots and then i to move rearwardly inthe horizontal parts 7 of the slots. During thisoperation, the

arms 9 iirst swing upwardly andthen downwardly into parallel relation tothe sides of the frame 1,'.the' wall 19 of the receptacle 11 being swungto an open position by the connection 22, as shown in Fig. 1. Vhen therollers 14 on the receptacle 11 pass into the horizontal parts 7 oftheguide slots,l the rear ends of the arms 42 on thie doors 33 engage thestandards 43 and slide downwardly along the forward surfaces thereof.the arms passing rearwardly across the inclined lips 44 of thestandards. The engagement between the arms 42 and the standards 43closes thev doors 33 and when 1 -the doors arrive at a closed position,the

latches 38, under the action of the springs 41, engage in theirnotchedportions 4() with the keepers 36, to hold the doors closed.

The parts are now restored to the position 15 of Fig. 1 and thereceptacle 11 is so placed as to receive the sheaves of another shock.

It has been pointed out hereinbefore that the lever 53 is manipulatedtoY swing the arms 9 upwardly and to dispose theereceptacle 11 in avertical position at the ltime the shock passes out of the receptacle.When the rollers 14 move downwardly in the parts 8 of the guide slots,it is desirable that the liexible' elements 56 be permitted to pay outwith a run, and in order that this may be done, the clutches 52 aredisengaged automatically from the drumsV 51 as follows: When the forwardends of the arms 9 swin upwardly, the extension 65 and the cam 6 on onearm Fig. 4) move downwardly, the cam 67 operating the lever 53 so thatthe drums 51 no longer are connected lwith the shaft 50 by the clutches52. Likewise, it is desirable that the llexible elements 64 be releasedat an appropriate time as the receptacle swings downwardly into thereceiving position of Fig. 1. It is for this purpose that the rock shaft68 is provided. When'I the connection 22 swings upwardly, the bar 23thereof engages the finger 70 and rocks the shaft 68 by means of the arm69, the arm 71 causing the cam 72 to shift the lever 62 therebyretractin the clutch 61 and setting the sleeve 60 an its drums 63 freefrom the shaft 50.
